Starting November 1, the Telecom Regulatory Authority of India (Trai) will enforce new rules requiring telecom companies to trace messages from banks, e-commerce, and financial institutions to prevent spam and fraud. However, telecom operators warn that these regulations could disrupt essential services like one-time passwords (OTPs) and transaction notifications. With around 1.5-1.7 billion commercial messages sent daily in India, any delay or blockage due to incomplete technical compliance from telemarketers could affect millions. Telcos have requested a two-month extension to allow more time for message providers to update systems.
